Passive solar control solutions have been widely used in buildings in tropic countries like Malaysia. It is assumed that these solutions may notably control the heat-gain of buildings. However, there is a lack of empirical studies that assess the extent of green-glazed techniques to sufficiently control solar heat-gain. The current study uses a case study approach to examine the thermal indoor performance, particularly the near-glazed workplace area. The performance of the ST Diamond Building (in Putra Jaya, Malaysia) has been examined in terms of: outdoor/indoor dry bulb temperature; glass surface temperature; heat flux through glazing; outdoor/indoor air movement; lux and; solar radiation. The results of the field analysis indicated that ST Diamond Building’s green-glazed solutions are efficient to control solar heat gain, which in turn will lead to reduce energy consumption for controlling solar heat loads.
